hey there Goatkeeper. I run the great beyond podcast (thegreatbeyond.libsyn.com). Support groups are good, but I'm not sure we could keep one running. Even though its nice to hear there are other short fiction podcasts besides myself, come let me whisper, and a couple of others (including escape pod and pseudopod), I don't we could keep one going.
As for tips, I could give you one really good one.
never, never, Never, NEVER NEVER NEVER ever use the audacity audio cleaning option.
As for exchanging promos, I'd love to actually. I'm always for helping out each other. Send me down an email at thegreatbeyondpodcast(at)gmail(dot)com
